To all eas/1.0m it may conce/m.' f

Be it known that "I, AUGUsr SUNDH, a citizen of the United States,residing in Hastings-uponludson, in the county of estchester and Stateof `rlew York, have invented a new and useful Improvement in HingeMechanisms, of which the following is a specification.

My invention relates to hinges for use on doors, gates, and the like,and is particularly adapted for usein situations exposed to the weather,and where they receive no particular care. It is a matter of commonknowledge that outdoor hinges or hinged gates seldomvworlr perfectly.This isvdue largely to ineliicient lubrication, and because the hinges.`springs, and other kmechanism are subjected to the elements and rust andwear rapidly, and also becomecl'ogged up with mud, ice, etc.

An object of my invention is to overcomer these objections, and provideran automatic self-closing gate having 'zi-hinge inclosed vin a casi-ngwhich forms an oil reservoir so constructed 'as `to prevent rust, or`the access of water, dirt, ice, or any-thing to interfere with theperfect working yof the' mechanism.

Other objects `of the invention and the exact nature thereof will appearhereinafter.

Referring Ito the accompanying drawings, Figure 1 is a sectionalelevation y view of hinge mechanism constructed in accordance with myinvention, and also showing a portion of a gate attached thereto ;4 Fig.2 is a sectional 'elevation view ,of the hinge mechanism taken on aplane at righty angles to that of Fig. 1; 3 is a'sectional view as`indi'cated by the line 3-3 'on Fig. Q; Fig. eis sectional view as indicatedby the line on Fig. 1; Fig; 5 is a view showing a gate with my -improvedform of hingeattached thereto;` Fig. '6 `is a similar view showing amodified arrangement for attaching the gate to ,its support. o A

The gate G, as shown in Fig. 5, is hinged to a gate post 1 by means ofthe hinge mechanism A, 4nmunted 'on the upper end of the post l `andlower hinge 2; fthe latter is in the' form of astrap or heavy band looseon the postand riveted or otherwise secured to the gate. Thisarrangement permits the gate to move up and `down freely, as herein setforth; A dummy A', corresponding in outward appearance to the device A;may be mounted on the opposite gate post.

tail. infigs. 1 and 2, comprises a stationary member 3, the upperportion of which is in the 'form of a cylindrical receptacley 11. Depending `l'rom this receptacle is an extension 5 adapted to enter thehollow post 1. Ribs 6v formed on the extension o,have a tight t in thepostand secure the member 3 rigidly in positioi'i. These ribs may be ofsullicient depth to slightly spring the postl vtr-hen driven into place.Extending upward within. the receptacle is a tubular projection orsleeve 7. `The opening through the exten.- sion 7 is continued downwardinto the 'projection 5J as shown, and forms a cylinder or k'socket toreceive a vertical pivot pin or pintle 8. This' construction provides along vertical .bearing surface between the hinge members, which reduceswear to a minimum and 4prevents the-gate from sagging.' Rigidly securedto the pintley S is a movable hingey member 9. The latter is in the formof a hollow cylinder or sleeve with a portion cut away vto form inclinedbearing surfaces 10. The latter cooperate with an anti-friction roller11 mounted for rotation on a pin 12; Said pin is threaded into thewallof the `oil chamber or receptacle e, and also has a bearing in theextension 7. The roller 11 is frustoconical in shape so as to present aninclined bearing surface, `on which the inclined surfaces 10 of themovable hinge member are adapted to roll. 10 are substantially spiral orhelical, so that the pitch is uniform throughout. Mounted on the hingemember 9 is a protective device 13 forming a cap or cover for thereceptacle e, an'dffparts contained therein. An outer flange `1i'extends downward outside of the oil chamber e, and an inner annularflange 15 entends downward` within the oil chamber. Theliange' 15 formsa squared opening 16 with its sides vflaring outwardly and downwardly toreceive the upper squared end `1'? of the rotary hinge member. lt willbe observed that the coperating 4surfaces of the `darts 15 and 17 aresomewhat diverent to permit a limited swinging movement of the member 13in the plane 0f the gate to accenimodate'the .latter if the hinges arenot in exact vertical alinement. rl`his Aadjust#r The surfaces ment ispreferably permittedonly in one `dif rection;` the bearing surfaces atright angles being preferably a close-ht, as indicated in Figft: with anextensionA I2() forming a socket to receive a `v"section 21 -of thefence.' The -oil The member -3 be provided casing is adapted to containa suitable lubri eating oil which when the member 9 is in its loweredposition completely covers the bearing surfaces l0 and 11. T he pintle8, which forms a pivot member is adapted to rotate freely and also tohave a vertical movement in the cylindrical opening through the parts 5and 7. rhe groove or recess 22 extends from the lower end of said rodupward to a point beyond the upper end of the/projection 7. T he purposeof this groove is to permit the escape of oil fromthe lower end of thecylinder as the rod descends, and to permit the entranceof oil as therod is lifted. Said opening` may be of such size as to throttle thefluid more or less as the gate'swings to a closed position, and therebyeffect a dashpot action, preventing too great an acceleration of thegate as it swings by gravity to its closed position. A bracket 24preferably cast integral with the 'cover member 13 forms arigid'connection between the latter and the gate.

The operation of my improved hinge mechanism will be apparent withoutany extended explanation. As the gate is swung open in either direction,the hinge member 9 is compelled to rotate with the gate and the inclinedsurface l0 rides up the roller 11, thereby lifting the gate in avertical direction through a distance proportional to its swingingmovement. When the gate is released its weight carries it downward andVthe inclined bearing surface 10 causes it to swing to closed position,where itl is automatically fastened by a latch device 23. The latter ispreferably constructed in accordance with my invention as fully setforth in my co-pending application for patent on latch, filed of evendate herewith. As shown in Fig. l the gate and moving parts carriedthereby swing about a vertical axis extending through the center ofthepost 1.

In the arrangement shown in Fig. 6 the hinge devices A are provided bothat the top and near the bottom of the gate. In this instance thebrackets 25 are used to attach the hinges to the gate post. Y

As the hinge mechanism is fully inclosed and the relatively movablecontacting surfaces arekept in an oil bath and continually lubricated, asmooth, reliable and eflicient action of the mechanism is insured. Theparts are fully protected against they entrance of dirt, ice, snow orvforeign substances of any kind. They are also fully protected againstrust. The mechanism therefore does not quickly get out of order as dothe usual constructions in use at the Vpresent time.

f giving entire satisfaction. It will be understood that variousmodifications in the details-ofconstruction and arrangement ofr partsmight be made without departing from the spirit and scope of myinvention. I wish therefore not to be limited to the precise structuresherein disclosed, as the invention comprehends all such modificationsAas come within the scope of the appended claims. y
